Mass Transfer - Engineering
Q1: Component A is diffusing in a medium B. The flux NA relative to a stationary point is equal to the flux due to molecular difusion, ifA mass transfer is accompanied by reaction.
B diffusion of A is in stagnant medium B.
C molecular mean free path is high.
D there is equimolar counter diffusion.
ANS:D - there is equimolar counter diffusion. The flux 𝑁𝐴NA relative to a stationary point is equal to the flux due to molecular diffusion if there is equimolar counter diffusion. Equimolar counter diffusion occurs when two components, in this case A and B, are diffusing in opposite directions at the same rate. This results in no net movement of either component relative to a stationary point, as the movement of one component is exactly balanced by the movement of the other component in the opposite direction. As a result, the flux of component A relative to a stationary point is equal to the flux due to molecular diffusion. So, the correct option is:
